How to Measure Long Distances Precisely in Industrial Applications
The optoNCDT ILR2250 laser distance sensors are designed for large measuring ranges. They are used in industrial environments and offer different measuring modes for optimal exposure on demanding surfaces. These sensors provide precise measurement results with high signal quality independent of the surface, whether it's on metals, plastics, paper or textiles.
In factory and plant automation, large distances between the sensor and the measuring object must be monitored reliably. Micro-Epsilon has developed the optoNCDT ILR2250 laser distance sensor for these measurement tasks. The sensor covers measuring ranges up to 100 meters without a reflector. When using a reflector, the measuring range can be extended up to 150 meters. Their aluminum die-cast housing protects the sensors against harsh environmental conditions. The integrated optical interference filters provide the ILR2250 sensor with very good ambient light suppression.
Therefore, measurements are also possible in outdoor areas, such as for monitoring the travel paths of crane axes or drone-based distance measurements. Their innovative technology enables demanding measurements on different surfaces, such as paper or plastics, as well as metals and textiles. These advantages make the optoNCDT ILR2250 ideally suited to many industries such as the steel industry, and transport, logistics and conveyor technology.
The Measuring Principle
The optoNCDT ILR2250 works with a red semiconductor laser of a wavelength of 655 nm and is assigned to laser class 2.
The value of the phase displacement enables the determination of the distance with high accuracy. The measurement is triggered either by a control unit, a PC, a trigger signal or the auto start function.
Put In the Right Light
The laser distance sensor from Micro-Epsilon offers outstanding signal stability on numerous surfaces, which enables measurement results down to millimeter accuracy. This innovative sensor technology is almost independent of the material on objects with a reflectivity from 6 to 100 %. Therefore, it’s suitable for versatile applications on different surfaces.
Presets are available for various applications, providing a predefined configuration depending on the material or reflection. The AUTO measurement mode is used for dark or weakly reflecting measuring objects. It provides fast, automatic exposure control even on dark, reflective and distant objects. This measurement mode optimizes the measurement frequency of the sensor, depending on the signal quality, and therefore provides the best results even in difficult conditions. The "Fast" mode is suitable for dynamic measurements on moving objects and fast distance jumps with movements of up to 1.6 m/s.
Furthermore, users can select the "Accurate" mode for high accuracy and tolerance with distance changes, or the "Precise" mode for highest accuracy on well reflecting measuring objects. The sensor then measures at 20 Hz.
